Form the equalizing llfll'Fi are usually tlu vul' from its opnosilo owl portions. in llw opposilv nous o'l .YllHll illt iiwlwl plnlos 'lI-l liosv opposiln r-ml norliou-- 51w lliJ'ill'Wl provided with the depending lugs guides or pedestals; and said plates 13 are of such length that their flanged portions 14 fit over the faces of the respective channel members 5 of the column guides.

The end portions of the I-beam or equalizing bar 12 have perforations therein through which the securing pin 11 is passed. Preterably, the pin 11 fits tightly in the perforations in said equalizing bar, but is fitted loosely or rotatably in said-bushings 10 in the ears or lugs 9 of the journal boxes.

.Mounted on the tops ot'the equalizing bars 12, near the opposite ends thereof, and adjacent to the inner sides of the respective pedestals, are spring seats 15. Seated on these spring seats 15 are coiled springs 16 whose upper ends are seated in seats 17 bolted to the under sides of said side por ions 1 of the main truck frame. It will thus be seen that the equalizing bar or beam 12 is carried by the journal boxes which are to which the opposite end portions of said equalizing bar are pivotally connected: and the main truck frame being supported by the springs 16 substantially at the four corners and adjacent to the column guides which are permitted a vertical movement with respect to the journal boxes, the weight of the truck is equalized or balanced on the four journals, in the case of a four wheel truck. Obviously, however, the same arrangement may be applied to a six wheel truck. hat is, a pair of equalizing bars will be provided on each side of the truck, the meeting end portions of each pair being pivoted to the respective middle journal boxes. This construction being obvious, it has been deemed unnecessary to illustrate same in the accompanying drawings.

As above set forth, the equalizing bar is preferably an I-beam section, owing to its great strength in proportion to its weight. However, I do not wish to be limited to any particular cross section or channeled or flanged beam. Nor do I wish to be limited to a single or integral commercially rolled or pressed section, as it is obvious that the equalizer bar may comprise a built up or structural beam of two channel sections. placed back to back and riveted together, or of angle sections and plates.

By providing the straight equalizing bar or beam and connecting the san to the under side of the journal boxes, a much shorter member may be used. This minimizes the weight and, also, by the arrangement of the straight equalizing beam, as shown and de scribed, it is possible to omit the usual pedestal tie bars and tie bolts which are usually provided at the bottom of the pedestal, thus I saving additional weight.

While the equalizing bar has been illustrated as pivoted to the depending lugs 0r ears on the bottoms of the journal boxes,

- said main truck frame.

obviously there are other methods ing the equalizing bar to the both; journal boxes, either by means o straps suspended from the tops of the boxes otherwise. Therefore, I do not to be limited to the specific construction and M rangement shown.

What 1 claim is:

1. In a car truck, the comb" the journal boxes, of a main mounted above said journal her 1 ing depending pedestals fitted journal boxes and movable vertically e on, an equalizing bar beneath truck frame and extending under t tive journal boxes and secured to means on said equalizing bar ineei of its connection with the joura slidably engaging said pe tals. and interposed between said eii ualizing said main truck frame.

In a car truck. the comb the o'urnal boxes, of a subst equalizing bar hingedly con posite ends to the under sides of i i tive journal boxes by pivot studs transversely therethrough.

in a car truck, the combina the journal boxes having depen on their bottoms, of an equali bar otally connected at its opposite ids to the lugs on the adjacent journal boxes by pivot studs extending transvers: y therethrm in a car truck, the combination v.) h the journal boxes, of an equalizer con prising a straight horizontal bar whose opposite end portions are hingcdly concerted to he respective journal boxes at the under sides thereof, and means on the equalizing bar slidably engaging the truck frame llltitfi ll h 1 ent of the connection between the equalizing bar and journal boxes.

5. In a car truck, the combination with the journal boxes, of an equalizer romprising an I-beam whose flanges are removed be from its opposite end portiims and \\'ll(), end web portions are UUIIIAOFl'tll to the respective journal boxes at the under sides thereof.

6. In a car truck, the combination with i the journal boxes, of a main trunk ti'zmie mounted above said journal boxes. 'iedeslals secured on said main frame and depending therefrom, said pedestals being titted over the respective journal boxes so as to'permit relative vertical movement thereof, equalizer beams at the sides of said truck, each equalizer beam having its end portions secured to the respective ournal boxes at the under sides of said journal boxes and being slidably connected to said pedestals to permit relative vertical movement thereof and serve as a tie rod for the truck frame, and springs interposed between said equalizer beam and root-wee in. cur truck, the combination with the journal bones, of 2V main truck frame mounted above said journal boxes, pedestals on 'd main, truck frame and dcpendin liillfil rom, said pedestals being elidehly fitted over said journal boxes so as to move vertically thereon and the lower portions oL-t said pedestals being slotted verti eolly, on equalizer comprising a hanged beam ose op iioeite end prtions are elidably ed through the vertically slotted portions solid pedestals and connected to the respecjournal boxes at the under sides thereof, uides on said flanged beam adapted to'hlidd a the respective pedestals so an to move vertically thereon but; preventing endmovement with respect to them, and springs interposed between said flanged mid mid main trucl: frame. i o car truck, the combination with Pool loo s, of a main truck frame, lestole secured on Said main truck frame boxes so to move vertically r on, an equalizer beam located below no main truck frame, the intermediate portion of the equalizer beam being of L" notion, said been: being hingedly connected at its opposite ends to the adjacent journal boxes, guide flanges on the end por lions said equalizer bean] elidably en gaging the :ufljacent pedestals St) or; to permit vertical movement oi the pedestals with and rr vent to aaid equalizer beam but prevent independent cudu'ise movement thereof.
